2 Claims.

This invention relates to a resilient mounting,-

and more particularly to a resilient mounting for motors and the like.

It is an object-oi' this invention to provide a` resilient mounting for a motor which permits the 30 i0, having a vertical axis of rotation, has a base' motor to be easily removed therefor. f

Another object of this invention is to provide a resilient mounting for a motor that is particularly adapted to the mounting and support of a motor having a lvertical axis of rotation.

Another object of this invention is to provide a resilient mounting for a motor, which mounting prevents rotation of the motor relative to the support therefor.

Further objects and advantages of the present invention willxbe apparent from the following description, reference being had to the accompanying drawing wherein a preferred embodiment of one form of the present invention is clearly shown.

In the drawing:

Fig. 1 is an elevation of a motor provided with a mounting embodying the present invention, with parts thereof shown in section.

Figs. 2 and 3 are fragmentary sectional views of resilient mountings embodying modified forms of the present invention.

With particular reference to Fig. 1, a motor member I2 that is provided with a base portion I t that preferably has a substantially conical outer surface. The base portion I4 is preferably integrally formed with the base I2. A support member I6 preferably has a substantially conical surface I8, the axis of whichsurface preferably coincides with the axis of the conical surface of the base portion I4. A resilient member 2U, pref erably made of rubber, Duprene,l or other suitable resilient material, has substantially conical inner and outer surfaces 22 and 24 respectively, which surfaces lt those of the base portion I4 and support I6.

The resilient member 20 has portions 26 and 28 projecting inwardly and outwardly respectively, from the inner and outer surfaces 22 and 24 thereof. The projecting portion 26 projects into a recess 30`in the base portion I4, and preferably conforms to the surfaces or walls of the recess 38. A projecting portion 28 projects into a recess 32 in the support I6, and preferably conforms to the walls of the recess. 'I'he recesses 30 and 32 preferably have walls 34 and 36 respectively, that are substantially parallel to the axes of the conical surfaces to facilitate removal from the support' (ci. 24e-2G) of the resilient member 20 therefrom. A portion 36 of the base member l2, preferably integrally formed therewith, overhangs the insulating member 28 and support I6, and vent lubricant and foreign substance from reaching the surfaces of the resilient member 20. 'Ihe flange member 38 on the support member I6 has an aperture 8) therein, and is adapted to be secured to a suitable mounting support to mount the motor.

The particular motor shown in Fig. 1, isv of a type utilized in the processing of textile material,

and has abucket portion 52 at the top thereof,`

and a skirt portion d3 that forms a part of the motor housing; however, it is understood that the present invention is not limited to that particular type of motor. The operating current for the motor is provided through a suitable cable i4 that extends into the base of the motor and is anchored to that base by clamping means including an external nut 46 made of insulating material.

With particular reference to Fig. 2, theibase I2 has a substantially cylindrical base portion 58 preferably integrally formed therewith. A sleeve member 52 fits over the base portion' 58 and is held in place thereon between the flared portion 55 of the base and a locking ring56 that ts into a groove 58 in the base portion 50; Flanged annular members 60 and 62 having their flanged portions 64 and 66 respectively, adjacent, surround the sleeve 52 and are preferably that is preferably thereby tends to precoaxial therewith and spaced therefrom. A layer of resilient material 68 that forms a resilient member lls the space intermediate the members 60 and 62 and a sleeve 50, and is preferably vulcanized thereto. 'I'his resilient layer or member may be made of rubber,`Duprene, or other suit- -abl resilient material. The flange portions 64 and 66 have apertures 18 and l2 therein and rest against a support member '1 4 having corresponding and aligning apertures 16 and i8 respectively therein, which apertures accommodate mounting bolts 80 and 8 2 respectively. 'Ihe bolts 80 and 82 have cooperatingnuts 86 and 86 respectively, and serve to secure the motor to the support 14. opening 88 through which the base portion 58 and resilient mounting project. The annular -member 62 is spaced somewhat from the wall of the aperture 88. The motor is thus supported through the resilient member 68.

With particular reference to- Fig. 3, the base I2 has a substantially cylindrical portion 90 integrally formed thereon and extending through The support 14 is provided with an an opening 92 in a support member 94. A layer of resilient material or resilient member 96 is interposed between a plane surface 98 on the base |2 and a planesurface |00 on the support 94, and surrounds the cylindrical portion -so that the motor is supported therethrough. A metallic disc member |02 is preferably interposed between the resilient member 96 and the support 94. The base portion 90 is preferably spaced from the wall of the opening 92 so that the support-is obtained entirely through the resilient material. A pin |04 is preferably driven into a aperture |06 in -the base I2, and extends through an aperture |08 in the resilient member 96 and disc |02, and into an opening ||0 in the support 94 to locate the motor circumferentially, and prevents circumferential movement of the motor relative to the support 94. The motor is resiliently secured to the support 94 through a layer of resilient material or resilient member ||4 having cooperating metallic disc members ||6 and ||8, all of which surround a portion of the base portion 90, and are disposed intermediate a nut |20 that is threaded onto a threaded surface ||2 of the cylindrical portion 90, and the support member 94. y

In the operation of the device shown in Fig. 1, the resilient member 20 fits into the conical surface I8 of the support` I8 and is located therein by the projecting portion 28 that fits into the recess 32. The conical surface of the base portion 4 then fits into theinner surface of thev resilient member 20 and is located therein by they projecting portion 26 that fits into the recess 30. The cooperating projecting portions and recesses thus serve to locate the motor circumferentially, as well as to prevent circumferential movement of the motor relative to the support I6. By making the walls 34 and 36 of the recesses 30 and 32 respectively, substantially parallel to the axes of the conical surfaces, the motor may be easily axially removed-from the support. Since rubber and similar resilient materials are deteriorated by oil and other foreign substances, the oyerhanging portion '38 on the base |2 is provided to prevent such substances, as well as dirt and grit from easily reaching the surfaces of the resilient material.

In the device shown in Fig. 2, the weight of the motor, which is supported through the resilient member 68 establishes a shearing stress in the resilient material between the surfaces adjoining that material.v Hence, the resilient material is preferably vulcanized to the sleeve 52 and flanged annular members 60 and 62. In this form, the sleeve 52 preferably fits snugly upon the cylindrical portion 50 so as to provide a firm support for the motor and to'prevent circumferential movement of the motor therein. The motor is then located and held against circumferential movement relative to the support 14 by the bolts 16 and 18, and the cooperating apertures in the projecting flanges.

In the device shown in Fig. 3, the motor is supported through direct compression of the resilient material. In this form, the motor isl circumferentially located and prevented from circumferential movement relative to the support by the pin |04.

While the form of embodiment ofthe present invention as herein disclosed, constitutes a preferred form, it is to be understood that vother forms might be adopted, all coming within the scope of the claims which follow.
